unsatisfied customer

The fridge that I purchased from Defy stop working last year April so I called Defy and they sent a technician out on the 19/04/19. The technician advised for the following items to be replaced: Compressor Filter A glass Drier I ended up paying R 4673.51 for the repair of the fridge. Last month my fridge stopped working again and they sent out a technician which come up to R 630.00 which I paid. He said to me the compressor in my fridge is a small compressor and not one of Defy's products but it was a compressor replaced by them. Now I'm really upset by the ordeal and I don't know what to do anymore.
